I V Mylinvention,irelates to package j sealing machines and more particularly to package sealingmachines which will moisten theseal-v ing paper or gummed paper entirely to both v 5 ends of the sealing paper section; .anduthe object is to provide simple machines which are highly efficient for cutting and. moistening gummed-service paper for sealing packages andwhich can be manufactured and in- 10 stalled at relatively small costs Other objects and advantages will be fully"ex'- plained in the following description and the invention will be more particularly pointed out-in the claims. f I

A wedge 3 is placed in thecompartment 1 in front of the gpaper roll 5' and this "weight will follow the paper rolldownwardly as the paperroll becomes smaller. Inthismanner the paper-roll will notmove so far when a section of paper vis drawn forward tobe cut off. An adjusta ble paper roll holder is provided and placed 'lIlLSlClBlOf the compartment 1 and consists of two parts 6 and 7. This arrangement is best shown in Figure 4 whereinitwillbe seen that the-parts 6'and 7 are of the general form of arcuate'angles having overlapping legs 6a 'and 7a, these legs being rabbeted as shown.

One leg a'sia, is provided with transverse slots 7?) .through which pass suitable screws as 6.6 so that the two members when assembled I form an arcuate channel adj ustable. for width and adapted to be secured in adjustment by [said screws. The parts 6 and 7 aremovable towards} and from eachother while their bottom members slide. against each other.

Thec mPartment-Q contains a supply of 11 ,for the compartment forms a part of the Figs." 1, 2, and 3, the cutter 9 and the feeding ally connected to the compartmentby bolt'12 and has its swinging front end .releasably latched down to cover the compartment 2 by latches 14 which engage'lugs 13. A small ompartmentlti is formedin the compart-s "feeding mechanism. In the form shown-in 1 v ment 2 for themoistenerbrush by means of a partition 17 which has perforations 18 so that water can pass from the larger compartment 2 into'the brush compartment or holder 16. Means are provided'forrholding the brush 15 against the end of the cutting devices 9. A flat perforated plate 19 is pro-jvided to stand up against the m-oistening brush 15 and a spring plate 20 is attached to the brush 15 and plate 19.

In order to prevent this moving ofthe machine, supporting bars 29 are pivotally connected to the bottom of the machine and at each endyeach bar has cavities to receive rubber feet or supportsBO. The

rubber supportsor feet will be yielding so thatthey will yield slightly backwardly but they will not slip on the table or counter and the elasticity of the rubber will bring the machine back to the required position. The supporting bars 29 serve to prevent the machine fi'rom turning over: because they substantially extend the base: The bars 29 can be-turned longitudinally of the machine for one advantage "ofmaking the cover tegaral: with the cover 8 is that the cover 9 packing and shipping purposes.
